One in Three Maine Districts at Record-Low Enrollment

In this series: Maine 2025-26 Enrollment.

Portland Public Schools lost 253 students this year. That is not what makes the number notable. What makes it notable is where the loss left the district: at 6,302 students, Portland is at its lowest enrollment in at least a decade, the floor of the available data. The state's largest school system has never, in any year on record, been this small.

Portland is not alone. Eighty-three of Maine's 214 districts with at least eight years of enrollment history are at their all-time low in 2025-26. That is 38.8% of the state's districts, and the list includes not just the rural RSUs where small size makes volatility routine, but Scarborough, South Portland, Augusta, and eight of the state's 20 largest systems.

The three-year slide

Maine's statewide enrollment peaked at 180,917 in 2016-17 and has fallen to 168,923, a loss of 11,994 students, or 6.6%. The trajectory matters more than the total. After a brief post-COVID bounce in 2022 and 2023, the decline has resumed and is accelerating: the state lost 1,307 students in 2023-24, 1,562 in 2024-25, and 2,134 in 2025-26. This year's drop is the largest non-COVID loss in the dataset.

The year-over-year pattern shows the shift clearly. The two recovery years after COVID, when 756 and 700 students returned, now look like a brief reprieve. The three-year decline since 2023 totals 5,003 students, more than erasing the post-pandemic gains and then some.

Where the lows are concentrated

The 83 districts at record low are not clustered in any one part of the state. They span Portland (6,302 students) down to tiny communities with enrollment in the double digits. Eleven of the 83 enroll more than 2,000 students. Twenty-one enroll fewer than 100.

Among the largest districts at their floor, Portland's 7.0% decline from its 2020 peak stands out, but South Portland's trajectory is steeper in relative terms: down from 3,081 in 2023 to 2,750 in 2026, a 10.7% drop in three years. The suburban ring that once absorbed overflow from Portland is now declining alongside it.

Only 57 of 214 districts grew between 2025 and 2026. Lewiston (+36), Auburn (+66), and Biddeford gained students, a pattern consistent with their roles as immigrant-receiving communities. Maine Virtual Academy added 23 students, continuing a nine-year growth streak that tracks national virtual enrollment trends.

Meanwhile, 146 districts shrank. The decline is broad enough that the median all-time-low district enrolls just 522 students.

A share that keeps rising

The percentage of districts sitting at their all-time low fell to 27% in 2023 as post-COVID recovery lifted many systems back above their 2021 troughs. That recovery has stalled. The share climbed to 31% in 2024, 32% in 2025, and 39% in 2026.

Two districts have been declining for seven consecutive years without interruption: RSU 29/MSAD 29 in Houlton and RSU 49/MSAD 49 in Fairfield. RSU 49 was flagged by Bellwether's national research as experiencing double-digit enrollment losses over five years. Another six districts have decline streaks of five or six years.

Fewer births, more closures

U.S. births have fallen more than 20% since 2007, and Maine, one of 17 states with more deaths than births in recent years, has felt the squeeze acutely. In a state where two-thirds of districts enroll fewer than 500 students, smaller incoming kindergarten classes translate directly into budget pressure. The state's kindergarten enrollment is down 14.8% from its 2017 level, a pipeline signal that future years will bring more record lows, not fewer.

The operational consequences are already visible. More schools closed in Maine in the first half of 2025 than in all of 2024, according to the Maine Department of Education. RSU 4 shut down Sabattus Primary School, saving roughly $300,000 in annual costs on a building that opened in 1953. RSU 34 closed Viola Rand Elementary in Bradley after enrollment declined to the point where nine classrooms sat empty across two buildings.

"You're truly thinking of all communities as one." -- Matthew Cyr, superintendent, on regional school consolidation

The closures echo a longer-running tension in Maine education governance. The state's 2007 consolidation push merged many districts into Regional School Units, but communities have continued to debate whether those mergers serve them. Last June, Embden voters rejected a proposal to withdraw from RSU 74 by a 148-107 vote, a margin that reflects the pull between rising property tax burdens and the fear of losing a community's school identity.

Portland's budget math

Portland's record-low enrollment carries direct fiscal consequences. Under Maine's Essential Programs and Services (EPS) funding formula, state aid follows students. Portland expects to receive $4 million less from the state next year, driven by both enrollment losses and rising property valuations that reduce the district's state subsidy.

The proposed budget cuts 20 positions, including teaching slots tied directly to enrollment decreases. Across the three largest southern Maine districts, Portland, South Portland, and Lewiston have proposed budgets that would cut a combined 128 positions, with South Portland alone looking at nearly 80 reductions.

The EPS formula itself is under scrutiny. A bill to reform the long-criticized formula received broad district support at a legislative hearing in March 2026. Proposed changes include factoring local poverty rates into a district's ability to pay and updating regional cost adjustments. For districts already at record-low enrollment, the question is whether any formula revision can offset the arithmetic of fewer students.

What the data does not settle

The 38.8% figure is striking, but it carries structural caveats. Maine's SAU system means that many of these "districts" are small enough that a single family moving can shift enrollment by percentage points. Twenty-one of the 83 districts at all-time low enroll fewer than 100 students; for them, the record may reflect normal volatility rather than secular decline.

At the other end of the scale, Portland's decline from 6,779 to 6,302 involves hundreds of students and real budget consequences. These are different phenomena sharing a label. The fact that 38.8% of districts are at their floor is less important than who is on the list.

Only 22.4% of Maine's districts have recovered to their pre-COVID enrollment levels. Governor Mills' Commission on School Construction has put a number on the infrastructure mismatch: 500 of the state's roughly 600 school buildings need renovation or replacement within 20 years, at an estimated cost of $11 billion. Those buildings were built for 180,000 students. They now hold 169,000. The commission's report mentioned consolidation as part of the long-term strategy, then noted what every town meeting in Maine already knows: communities do not want to send their children to another town's school.
